Liberator

When mild-mannered Professor Nelson Drew discovered an ancient Egyptian formula called "Lamesis," he used it to give himself super-powers and became The Liberator.

With his increased strength and speed, and his red, white, and blue outfit, The Liberator battled the usual array of spies, saboteurs, and fifth-columnists for three years, before fading into obscurity and the public domain.

Loki

Although raised together, the differences between Loki and Thor were evident, with Thor being a strong, brave, and fierce in battle, while Loki was more cunning, clever, and slowly becoming a sorcerer.

As Loki became more angry and resentful, he began dreaming of ruling Asgard. Briefly, he held the throne, but was overthrown by Surtur.

Later, Loki joins forces with Thor and Odin to fend off Surtur.

After the events of Ragnarok, Loki was killed, but has been reborn several times.
